Got a Photon project; What's next?

Hi there,
I have really got a general question about photon builds. I just started out using photon in unity, but I now finished my first project. I have build the application and the multiplayer works just fine if I run it on the same device. But once I had sent it to another computer, it doesn’t open anymore and macOS gives me a error message.

So I was wondering, if I want to sent my build to other people so that we can play my project in multiplayer, do I need to think of certain settings when building the project or think of different ways to send the project?

Thank you in advance for your help, I just wasn’t able to find the solution on my own.

Cheers

Are both machines Mac? or Is one machine Windows and your other is Mac
Because you have to Build to the target platform. The only way to build for Mac is to build on a Mac PC, no other way to produce Mac builds.

I was building the project on a Mac book for Pc, Standalone … for macOs and it worked just fine. Until I sent it over to our Mac where it wouldn’t open. I then build the same program for Pc, Standalone… for Windows and sent it to a friend for him to open it.

Turns out for windows it build a folder in which he tried to open the .exe file, which didn’t work aswell.

Would you assume this being an error in my coding or in the settings of my build or anything else?
